1.You must increase storage size in increments of at least _____

A.40

B.20

C.50

D.10

Answer:D

Explanation:

When modifying an Amazon RDS instance’s storage size, you must increase it by at least 10% of the current allocated storage.
This ensures a smooth scaling process and prevents excessive storage expansion requests that could impact performance.
AWS does not support decreasing storage size, so plan storage allocations carefully.

2.Manually created DB Snapshots are deleted after the DB Instance is deleted.

A.TRUE

B.FALSE

Answer:B

FALSE

Explanation:

Manually created DB snapshots are not automatically deleted when the associated RDS instance is deleted.
They remain stored in Amazon RDS until you manually delete them.
Automated backups, however, are deleted when the RDS instance is deleted unless you choose to retain the final snapshot during instance deletion.

3.Does Amazon RDS allow direct host access via Telnet, Secure Shell (SSH), or Windows Remote Desktop Connection?

A.Yes

B.No

C.Depends on if it is in VPC or not

Answer:B

Explanation:

Amazon RDS does not allow direct host access via Telnet, SSH, or Windows Remote Desktop Connection because it is a managed database service.
AWS handles maintenance, backups, and security for RDS, so direct access to the underlying server is restricted.
Instead, you can interact with the database using SQL clients, APIs, or AWS Management Console.
If you need full control over the database server, consider using Amazon EC2 with a self-managed database instead.

4.If I modify a DB Instance or the DB parameter group associated with the instance, should I reboot the instance for the changes to take effect?

A.No

B.Yes

Answer:B

Yes

Explanation:

If you modify certain DB instance settings (e.g., instance type, storage, or networking), a reboot may be required for the changes to take effect.
Changes to a DB parameter group may require a reboot depending on the parameter:
- Dynamic parameters take effect immediately.
- Static parameters require a manual reboot for changes to apply.

5.You must assign each server to at least _____ security group

A.3

B.2

C.4

D.1

Answer:D

Explanation:

Every Amazon EC2 instance must be assigned to at least one Security Group when launched.
Security Groups act as virtual firewalls, controlling inbound and outbound traffic to instances.
If you do not specify a custom security group, the instance is automatically assigned to the default security group in the VPC.
You can associate multiple security groups with an instance, but at least one is required.
